OK, so first off, I scaled it down to 1x and changed the viewport to show the entire puzzle. Next, I set the default speed to 4 since there is no timing involved.Then I made it so the thing you have to click to start the level is visible, as I got confused after accidentally clicking the start pink too soon.But the thing I really disliked is that your "L" mechanism let one ball through. So I tested a replacement using a spring. Still not sure if it has any bugs.
